This note presents a largely automated method to create bathymetrically safe,legible, scale appropriate depth contours for Electronic Navigation
Charts (ENCs)using the CARIS BASE Editor version 4.4 software installed in the AustralianHydrographic Office (AHO). The method is suitable for contouring modern high
densitymulti-beam survey data as well as sparser single beam data (or a combination ofboth). Being a largely automated process, the time required to incorporate
newbathymetric data into navigation products is significantly reduced. The methodfacilitates finer resolution depth encoding within ENCs and therefore a more
realisticportrayal of safe water to the mariner.
